2. What are therapeutic
procedures?
 Procedures in which the patients
experience relief from a symptom, a
stop to the development of a disease,
or some other short or long term
assistance.

3. Extracorporeal Circulation
 What is it?
◦ Used to sustain the patient’s blood circulation
and/or lung function outside the body during
open-heart surgery.
 How is it done?
◦ Using a heart-lung machine.
 What does it do?
◦ Deoxygenated blood is taken out of the body
and enhanced with oxygen by passing it
through an artificial lung (oxygenator), before
being pumped back into the patient’s
circulation for up to six hours.

4. Extracorporeal Circulation

5. Ligation and Stripping
 What is it?
◦ a minor surgery, used to remove a
varicose (damaged) vein and prevent
complications of vein damage.
 How is it done?
◦ An incision is made below the vein, a
flexible instrument is threaded up the vein
to the first incision, and the vein is
grasped and removed.
 The vein is tied off (ligation), and removed
(stripping).

6. Ligation and Stripping

7. Percutaneous Transluminal
Coronary Angioplasty (PTCA)
 What is it?
◦ The method for treating localized coronary
artery narrowing.
 Why is it done?
◦ performed to open blocked coronary arteries
caused by coronary artery disease (CAD)
and to restore arterial blood flow to the heart
tissue without open-heart surgery.
 How is it done?
◦ special catheter (long hollow tube) is inserted
into the coronary artery to be treated and is
inflated.
 The inflated balloon compresses fatty tissue in the
artery and makes a larger opening inside the artery
for improved blood flow.
